In your service check_command, you are specifying the following --
check_command = check_ldap
$ARG1$ = dc=ifi,dc=uzh,dc=ch
$ARG2$ = -3

Based on the check_ldap command definition you provide,

/usr/lib/nagios/plugins/check_ldap -H '$HOSTADDRESS$' -b '$ARG1$'

nagios is being told to run --

/usr/lib/nagios/plugins/check_ldap -H 'value of "address" parameter  
from host definition' -b 'dc=ifi,dc=uze,dc=ch'

This is different from your command line test (below) in significant  
ways that will cause it to fail.

check_ldap -H host.ifi.uzh.ch -b dc=ifi,dc=uzh,dc=ch -3

I'd suggest reading the documentation on Using Macros in Commands.
